The present invention relates to improvements in apparat-us of the class adapted for use in the dyeing or other treatment of yarn or other textiles While wound into cops,

ispools,` bobbins, cheeses or other package forms.

An object of the invention is to provide novel and improved means for mounting the packages and for supplying the dyeing or treating fluid thereto, whereby such Huid will be caused to pass uniformly through the yarn forming each`package, thereby ensuring thorough permeation of the yarn and uniform dyeing or other treatment thereof. 1,5 Another object is to provide novel and improved means for axially'cornpressing and supporting the yarn packages whereby the operations of assembling the piackages in the treatingrv chamber and the removal of the packages therefrom are facilitated, the

various packages being subjected to substantially uniform axial compression. thus minimizing or preventing leakage of the treating uid at the ends of the packages and ensurthrough the yarn comprising the packages.

To these and other ends the invention consists in certain improvements and combinations and arrangements of parts, all as will be hereinafter more-fully described, the features of novelty being pointed out particularly in the claims at the end of the specification.

In the accompanying drawings:

Figure 3 is a detail view ofl the upper portion -of .the yoke and screw partly shown 1n Figure 1.

Similar parts arev designated by the same o suiciently tightgolnt. A ittlng 54 1s secured reference characters in the several ligures.

The present invention, either 1n Whole or in part, is applicable generally to apparatus- T jsutable for use in the dyeing, mordanting,

ing uniform flow of the treating Huid4 preferred embodiment of the invention 4is shown in the accompanying drawings, and will be. hereinafter described in detail, but it is to be understood that the invention is not restricted to this particular construction as equivalents are contemplated, and such will be included within the scope of the claims.

The apparatus, according to the present invention, comprises generally a dyeing chamber or tank, and a structure embodying sets of hollow trays or similar members adapted to hold the yarn or other packages between them, said structure being adapted to be contained in said chamber and the packages to be so held between the hollow trays as to cause dye liquor or other Huid supplied to the chamber to pass uniformlyA through the packages to 'effect even dyeing or other treatment thereof, as will be hereinafter eX- plaine'd.

The dyeing chamber or tank comprises, in

the present instance, a bottom section or base 49 and a substantially dome-shaped shell or upper section 50 which is removable with respect to the base section to' enable the yarn packages to be placed preparatory to the dyeing or other treatment thereof and removed after 'dyeing or other treatment. As shown, the base section is provided with a ring. 51 adapted to receive and form a fluid-tight fit with a liange 52 formed ona ring at the bottom of the shell 50 and a suitable number of v clamping screws or bolts 53 are provided to draw these parts into contact to produce a to the bottom or base section toprovide the fluid passageway 10 which communicates with the interior of the dyeing chamber, and

. this fitting is provided with a Banged 'conduit Abe connected to a source 'of 55, the interior of which forms-the passageway 9. The passageway 10 may be connected to receive dye liquor'or other fluid 'from a suitable source, and the passageway 9 may be connected to discharge such liquor.- or Huid,

(or vice versa. A heating coil 56 is preferably y 'theyarn packages are adapted-to bemounted preparatory to the dyeing or other treatment thereof, and when the packages and the trays therefor have been assembled and secured the yarn packages will be subjected to axial compression 'which will produce substantially uniform l density lof the yarn throughout the packages, thus ensuring uni- `form dyeing or other treatment o'f'the'yarn 26- by reason of the uniform .permeation of the dye liquor or treating-fluid, and the yarn packages will form' at their endssubstantially fluid-tight joints with the trays so that the dye liquor or other fluid forced into the dye-1- ing chamber will bev caused to -flowfthrough the yarn composingthe packages withoutapf ,-preciable leakage vat the ends thereof. Furthermore, the present invention: provides a i f'noveland improved mounting for the yarn- 35.

packages 'whereby substantially uniform rate of flow of the dye liquor or treating fluid through all of the yarn packages is`obtained. For this purpose, each end ot each yarn package is engaged by and forms a huid-tight joint with a-hollow tray, the interiorsof the series ofl trays inter-communicating so that the pressure of the dye liquor or treating fluid will be substantially equal at the interior its interior bore.

In the construction shown, a set of trays 59 and a bottom tray 60 are shown, the trays 59 all being duplicates, and the bottom tray 60 being generally similanto the trays 59, but modified to adapt it to seat on the ange of the conduit 55. The bottom tray comprises upper and lower plates 61 and 62 which are spaced to forman interior chamber 63, and

` these plates are'rigidly connected at suitable points by stay members 64. A fitting 65 having a flange 6,6 is secured to the bottom of the tray 60, the flange 66 being'adapted to rest in a groove 67 formed in the top of the flange 68 on the upper end of the conduit 55 to form a substantially fluid-tight joint therewith. The inner portion of theI fitting 65 is webbed 'or otherwise formed to enable the dyel liquor or treating fluid to pass vertically through it. A plate 69 is fixed on the upper side of the tray 60, it having a groove 70 of each vyarn package and at both endsof therein to receive the joint-forming flange for 59 has aring 71 fixed to it and containing a .the tray next above it. Each ofthe trays I packing gla'nd 7 2 adapted to receivepacking vmaterial 7 if between it and the'ring 71, the lower' I,edge of the: packing gland providing the flange which engages in the groove u.70. The 4upper side of'feach of the trays 59 is provided with 'aplate 74 which is similar to the plate 69 on the upper side of the tray 60, it having a `'groove 5 therein to receive the lower edge of the packing gland of the trayv next above it. The packing glands 72 of all of the trays are webbed or otherwise formed te permit the assage, of the dye liquor or other treating uid therethrough. e The lower and upper plates 76 and 77 composing eachofn the trays 59 are spaced to form aninteri'orl e chamber 78, and these plates'are connected together at suitablepoiits by stay bolts or other suitable means to maintain them in properly spacedrelation.

The'trays are so constructed that'they receive the ends of the yarn packages between j them and will form substantially fluid-tight joints with the ends of the packages. As shownycp-shapedrseats 79 are applied to f Copposite faces ofv each tray, these seats Lbeing adapted to; receive and form joints with the ends 'of the yarn packages, the seats having apertures 80 therein to receive the ends of Y the holders 81 on' which the yarn is wound. Y

Holders of different kinds may be used, althoughjthese holders are of a size to fit the holder or bore in the wound yarn and .the holder is pervious to'permit the dye liquor or other treating fluid to flow therethrou h without 'substantial obstruction. Whent e endsof the holderswhich are of suicient length to project beyond the ends, of the yarn packages'are inserted in the central openings '80 in the seats on the trays, the'yarn packageswill be properly centered with respect to they seats and held in suchosition. The 'yarn^holders are tubular or ho low and open at the ends, and when the yarn packages have` been applied .tothe trays, the interior passages through the tubular or hollow yarn holders will chave unobstructed communication with the interior chambers Within the tra-ys, it being "nted that the ends of the holder of each package will directly communicate with the interior chamber of a trag 1 t fter-the yarn packages have been placed between each .pair of trays, such trays are held together by suitable means. Preferably,

a series of shouldered bolts 82 is provided for I ries are threaded into the upper ends of the bolts next below them. In addition, in orvder to distribute more evenly the compres-l sion maintained by the'trays upon the yarn packages interposed between them, series of olts 84 similar to the bolts 82 may be extended through tubes 184 which form openings in the portions of the trays between the center and the periphery thereof and at circumferentially spaced intervals around the trays, these additional bolts beingaccommodated in the spaces left between the rows of yarn packages. After each pair of trays have been 'assembled with the yarn packages between them, they are subjected to axial' compression, as, for example, by a suitable press, thus compressing the yarn packages axially to render uniform the density of the yarn composing eachv package and-to form substantially'fluid-tight joints between the ends of theyarn packages and the trays and on the upper edge ofthe conduit 55. Preferably, such means comprises a yoke 85 which may be bolted or otherwise fixed to the top of the dyeing chamber and a screw 86 extends through a bushing 87 which is revoluble in the top of the yoke and has a thread engagement with the screw, -the bushing being provided with a hand-wheell 88 for rotating it.. Bv this arrangement, rotation of l the hand-wheel and bushing in one direction will force the screw 86 downwardly, and the screw extends through al stuffing box 89 in the top of the dyeing chamber and bears at its lower end on a bolt 90 which cooperates with a head 91- to exert the compression on the yarn packages between the topmost tray and the tray next below it. By rotating the hand-wheel in a direction to force the screw 86 downwardly, the pile of trays will thus be forced downwardly, thus retaining the flange 66 in proper Contact with its seat on the top of the conduit 55. Before the screw 86 is thus adjusted, the clamping bolts 53 which hold the shell or upper section in place, are tightened.

W'hen the trays containing theyarn packages are assembled in the dyeing chamber.l the webbed member` and webbed glands 72 will form a continuous passageway from top to bottom of the assembled trays and in the center thereof for the flow of the dyeing liquor or other treating fluid, 'and ythis cen tral passagewaywill provide inter-communication with the interior chambers of the various trays. Furthermore, this central passageway through the trays and the hollow chambers within the trays is in communication with the passageway 9 at the bottom of the dyeing chamber, and this' latter passageway and the passageway 10 may be connected to anysuitable or well known piping, circulating pump and tank system for supplyingthe dye liquor or other fluid to and removing it from the yarn dyeing or treating chamber. When the dye hquor or treating medium is delivered to the passageway 10, such liquor or fluid will be forcedl into the portion of the dyeing'chamber exteriorly the yarn packages which are held and compressed between the trays. This dye liquor or treating fluid is forced into the dyeing chamber with suliicient pressure to force it through the yarn composing -thel packages from the outside to the center thereof, and the dye lquor or treating fluid afterreaching the centers of the yarn packages enters the pervious holders which form cores therefor, and the dye liquor or fluid then flows through the ends of the holders into the interior chambers of the trays, thence to the centrall passageway throughl the trays to the passage 9, and it returns to the circulating pump.

The direction of circulationof the vdye liquor or fluid may be reversed, in which case, the liquor or fluid enters the dyeing chamber through the passage 9 and flows upward- -ly through the central passageway in the ages, and the liquorl or fluid is then forced outwardly through the yarn composing the packages, and upon reaching the outside of the packages, flows into the passage'lO, and finally returns to the suction'side of the circulating pump. v

After the `packages of yarn have been properly dyed or otherwise treated, the shell or upper section 50 of the dyeing chamber is lifted from the base, thus exposing the pile of trays and the yarn packages interposed between them, and by loosening successively the central bolts 82 and also the supplemental bolts 84 and lifting the trays, the dyed or treated vyarn packages are removed, the apparatus being then ready for the mounting and dyeing or other treatment of another supply of yarn packages.-

While the invention has been described inv connection with the dyeing or similar treatl ment of packages of yarn, it is to be understood that the inventionis applicable alsovto packages of textile materials of other kinds lll) l compression, the interior chambers 'of the trays communicating with the respective ends of the packages.
